Flock Safety is a lot more than ALPR. They just try to fit in as an ALPR because those have been used for years. They do use their video feed to find unique identifiers of vehicles, such as dents, mods, color, make, model, etc. It's also highly likely they are doing facial recognition at some locations. I do not believe they are doing gait recognition yet for pedestrians, but it's just a matter of time.
I'm pretty familiar with the capabilities Flock actually offers law enforcement agencies, and it's license plates, makes, models, colors, and some identifying characteristics. This stuff isn't an abstraction, I don't have to reason about it axiomatically; you can directly engage with your local municipal government to see what's going on here.
